Answer:

Charlotte

Step-by-step explanation:

Uh, 224÷4 is 56 meaning Olivia types 56 words per minute, while, 348÷6 is 58, so Charlotte types 58 words per minute. So, I shall say that Charlotte types faster than Olivia.

Answer:

a = 54

Step-by-step explanation:

In geometry, the angles in a triangle add up to 180.

The unmarked angle at the top of the triangle = 180 - (a+10+44)

Or you could say that same angle = 180 - 2a because it is supplementary to the exterior angle... so

2a = a + 10 + 44

2a-a = 54

a = 54

The explicit formula for the geometric sequence -1/9, 1/3, -1, 3, -9, ... is -1/9(-3)^x-1 . What is the common ratio and recursi

KATRIN_1 [288]

Answer:

r=3
$\left\{\begin{array}{ccc}a_1=-\frac{1}{9}\\a_n=-3a_{n-1}\end{array}\right$

Step-by-step explanation:

Given the sequence

$-1/9, 1/3, -1, 3, -9, ...$

The common ratio is determined by the division of term by the previous term.

Common Ratio, $r=\frac{1/3}{-1/9} =\frac{-1}{1/3} =\frac{3}{-1}=-3$

A recursive formula is a formula that defines each term of a sequence using preceding term(s).

For the given sequence, the recursive formula is:

$\left\{\begin{array}{ccc}a_1=-\frac{1}{9}\\a_n=-3a_{n-1}\end{array}\right$
